RAILROAD-TIE.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application led December 26, 1908. Serial No. 469,429.

To all whom it may concern:

Be it knownV that I, THOMAS E. MCCOR- Miox, a citizen of the UnitedStates, and resident of Canton, in the county of Stark and State ofOhio, have invented certain new and useful Improvements in RailroadjTies, of Awhich the following is a specificathan the rail-carryingportion and that the plan view of the same.

bearing portion shall carry its greatest width between the rails andtaper to the outer end of the tie.

It also comprehends the location of a recess in the end of the tiewhereby the elastic rail-bearing member may be embedded in the frame anda recess for the adj ustment of the means that hold the elasticrailbearin'g member and the rail clip.

Heretofore in hollow metallic railroad ties it has been the custom tomanufacture the same in hollow pipe form of somewhat square shape incross section and in some instances to place metallic reinforcing withinthe same or to fill the same with cement and in railroad ties formedfrom a casting there has been noidea of hollow pipe casting but whatmight be termed a simple frame casting. Both vof these forms of tie haddistinct advantages yet neither of them could be termed a practicalrailroad tie and realizing the faults of both of these constructions Ihave devised a tie which in my opinion obviates all these dithculties atthe same time producing from a casting a hollow frame tie that is ofsufficient bulk to maintain its position and to so construct it that itcannot be dislodged without great diiiculty when it is once placed inposition.

To explain my idea Figure l represents a drawing of the side view of therailroad tie embodying my invention, showing part of the same insection. Fig. 2 represents a Fig. 3 is a vertical section on the line3-3 Fig. 1.

From an inspection of the drawing, more particularly illustrated in thesection disclosed in Fig. 3, it will be observed that the central partof the tie between the rails is cast hollow and that lateral ribsproject not only on the outside but on the inside and that the walls ofthe casting project below the level of the casting itself, forming ribsalong the bottom thereof and for the purpose of reinforcing the upperportion of the casting I have arranged one cross brace having lateralribs projecting therefrom in the same manner as the body of the casting.I have done this principally to save weight. It will also be observedthat the construction just described refers to the central portion ofthe casting or the portion between the rails and which for convenience Idesire to term the supporting portion.

The tie is constructed in this manner so that when the same becomesembedded in the earth the central portion acts as a wedge in the earthto form a solid foundation for and to resist any strain brought upon therails by the passing of the train.

To more fully describe the details of my invention, the tie may bedivided into two parts, the central portion between the rails and therail-carrying portion. The central portion between the rails is casthollow, the side walls a and b thereof projecting below the body of thecasting and forming the vertical projections for preventing the tie frommoving when once embedded in the earth. These side walls are alsoprovided exteriorly and interiorly with lateral flanges a a2, Z1 b2, thefunction of which is the same as the lower projection of the side walls.A vertical brace c is provided, extending along the upper portion of theties, which latter also carries lateral flanges c c2. From an inspectionof a sectional view of this construction it will be perceived that whenthe tie is embedded in the earth, the space on the interior and exteriorwill be illed with earth,

j practically making it impossible to move the tie when once set inposition; and to further provide that the earth may thoroughly fill theinterior of the tie, I have provided slots a3 and 3 in the side walls.It is my intention to construct these flanges with the exception of thetop brace, so that they shall be widest or project farthest between therails and gradually taper them to the outside end of the tie.

The end portions d of the tie are preferably cast with two recesses eand it, the recess e being parallel with the direction of the rail andso arranged that an elastic substance e', such as wood, may be insertedtherein for carrying the rail; and the other recess, h, being at rightangles thereto and so arranged that the bolt g of the rail-securingmeans f f shall project therein so that a nut attached thereto may beadjusted to hold the rail in position.

It will be observed from an inspection of F ig. l, that the hollowcentral portion and the rail-carrying portion are separated by a dam orbrace cl cl2, the upper portion al being inclined from bottom to top toform a brace for the lateral flanges c c2 of the vertical brace c andalso to save weight in the casting.

I have tapered the tie from the bottom to the top and also from asuitable point between the rails to the end of the tie, and I haveprovided the vertical brace c in the center of the tie so that should itbe desirable to embed the tie in cement for the purpose of streetrailroads a very small portion of the same would appear above thesurface and in this utilization of my tie it would be my intention tocountersink the rail so that the top of the same would practicallycoincide with the upper surface of the tie and also to provide an armhole at the end of each tie so that access can be had to therail-securing means within the recess below the rail.

It will be apparent from an inspection of the drawing that when a tiemanufactured in accordance with my invention is placed in the earth andthe earth suitably tamped or packed around and within it, the lateralanges and the vertical flange at the bottom together with the resistanceafforded by the vertical top brace with it-s lateral flanges render thetie absolutely immovable and that by a removal of a slight amount ofearth at the ends of the tie, the elastic rail-bearing means may beremoved and renewed and the life of the tie only limited by thecapability lset in said groove.

2. A railroad tie having, in combination,

a central slotted portion composed of a plurality of separated barshaving laterally eX- tending flanges, and a top portion provided 'with atransverse groove in each end, and

rail-bearing material of a substance differ ent from the tie secured insaid groove.

3. A railroad tie comprising a central slotted body the'sides of whichconverge toward its top, and the bars of which are flanged to provideanchoring portions and a rail-bearing portion at each end of the slottedportion provided with a transverse groove, and an elastic rail-bearingmaterial secured in said groove.

4. A railroad tie having a central body portion and rail-bearing endportions, each of the latter being provided with a transverse groove inits surface, and a longitudinal chamber extending from the end thereoftoward the anchoring portion and extending under said groove, arail-bearing block set in said transverse groove with its surface flushwith the surface of the central Y portion, and rail-fastening meanscarried by said block including bolts passing through the latter intosaid chamber. y

5. A railroad tie having, in combination, a central portion tapered fromits bottom to its top and end portions each tapered on its oppositesides and on its bottom from the central portion to its end, and arailbearing block carried by said end portion having its surface Hushwith the surface of the central portion.
